Abstract

Two sensitive techniques for temperature imaging by use of acetone planar laser-induced fluorescence, applicable at temperatures up to 1000 K, are introduced and demonstrated. Photophysics data on the wavelength-dependent temperature variation of acetone fluorescence permit the implementation of a single-wavelength technique in environments with constant pressure and constant acetone mole fraction, and a dual-wavelength method can be applied in flows with mixing and (or) chemical reaction. Preliminary imaging results are presented for acetone–air flow over a heated cylinder (single-wavelength strategy) and for a heated laminar jet (dual-wavelength strategy).
